DESCRIPTION
The LD29080 is a high current, high accuracy,
low-dropout voltage regulators series. These
regulators feature 400mV dropout voltages and
very low ground current. Designed for high current
loads, these devices also find applications in lower
current, extremely low dropout-critical systems,
where their tiny dropout voltage and ground
current values are important attributes. Typical
application are in Power supply switching post
SOT-223
regulation, Series power supply for monitors,
Series power supply for VCRs and TVs, Computer
Systems and Battery powered systems.
